Bedalr, M., and El Rassl, Z. (2003). Capillary electrochromatography with monolithic stationary phases III. Evaluation of the electrochromatographic retention of neutral and charged solutes on cationic stearyl-acrylate monoliths and the separation of water-soluble proteins and membrane proteins. /. Chromatogr. A 1013, 47-56. [Pg.475]

At least a very low water solubility of the monomer is required. Extremely hydrophobic monomers, e.g., stearyl acrylate, do not polymerize under emulsion conditions. [Pg.60]

It is well known that emulsion polymerizations of highly water-insoluble monomers such as octadecyl methacrylate (OM), dodecyl methacrylate (DM), and stearyl acrylate (SA) are generally not feasible using traditional surfactant... [Pg.78]

Hydrogels with hydrophobic, crystallizable side chains formed by copolymerization of acrylic acid and stearyl acrylate crosslinked with methylenebisacrylamide (BIS) showed a strong temperature dependence in their mechanical properties [91-93]. Such shape-memory gels having Tians = 7m displayed a reversible order-disorder transition associated with the interactions between the alkyl side chains. While behaving like hard plastic below 25 °C, softening above 50 °C enabled the materials... [Pg.18]

Preparation of PAMPS co-polymer gel is almost the same as that of PAMPS gel. The difference is just the numbers of monomers. Stearyl acrylate (SA), and acrylic acid (AA) were added to increase the Mechanical strength of the gel. [Pg.222]

The gel was prepared by radical copolymerization at 323[K] for 48 hours. The total monomer concentration in N, N-dimethylformamide was kept at 3.0M in the presence of O.OIM N,N - methylenebisacrylamide (MBAA) as a cross-linking agent and O.OIM a, a - azobis (isobutyronitrUe) (AIBN) as an initiator. Monomers were 2 - acrylamido-2- methylpropanesulfonic acid (AMPS), n-stearyl acrylate (SA), and acrylic acid (AA) with the composition (AMPS SA AA) = (20 5 75). After the polymerizations, the gel was immersed in a large amount of pure water to remove un-reacted reagents until it reached an equilibrium... [Pg.222]

Osada (1995), Kagami (1996) and co-workers have been pioneers in the study of hydrogels as SMMs. Firstly they studied hydrogels from acrylic acid (AA) and stearyl acrylate (SA) copolymers chemically cross-Unked with N,N"-methylene-bis(acryl amide) (MBAA) (Osada and Matsuda, 1995). Shape memory was obtained thanks to long hydrophobic regions from stearic acid contained in SA. These regions form a crystalline phase below 50°C and they act as a switching phase. This material has shape memory effect... [Pg.216]

Polymers where reversible shape memory is induced by a change in temperature are known as thermo-responsive ape memory polymers. For example, a hydrogel formed by acrylic acid and stearyl acrylate shows significant temperature dependent mechanical properties [128]. Below 50 °C, this hydrogel behaves like a tough polymer whereas above 50 °C it behaves like a soft material. This transition allows one to process the hydrogels above 50 °C, where they are easily malleable, into the desired shape, which can be... [Pg.126]
